Levy is a difficult last name to work with! I put a lot of consideration into how the firsts went with the last.
Boys, in order of my preference:NathanZacharyHenryToby- Doesn't sound very good with the last name, but Tobin and Tobias work fine and you can use Toby as a nickname.Leo- LeoLevy is too close.
(Middle name: Jordan or any of the above)
For combos, I like NathanHenry and HenryJordan best.

Girls, in order of preferenceZoeFayeAyaTova (nn Toby)- I really like this name, but TovaLevy is very v-heavy.Pearl- "Pearllevy" is how I hear it when spoken aloud, and I think Pearl is a bit clunky sounding anyway.
